The Center for Applied Linguistics (CAL) now offers periodic online instructor-mediated courses that teach participants how to administer and rate oral language proficiency for students in grades K-8 using the Student Oral Proficiency Assessment (SOPA) and the Early Language Listening and Oral Proficiency Assessment (ELLOPA).

Courses are offered when a minimum number of participants are interested in purchasing the course. Each course has a two month registration window. Participants have access to the course 24/7 and may work at their own pace with guidance from an experienced SOPA/ELLOPA trainer.
